To wn mtt my concern.- I in-g Bent known that We, EDWARD LJDAWES, off-Jen B'm'gl on Beaven'county. Pennsylr l q U Vania (1 Ct REED, oi Pittsburg.

5 North ide', nine-gustyco unty,' Pennsylvania, both citizens of the 'United States, have invented a certain new and useful Drain C"ne et 1 n;of 11911" the tollo'wing 1s a entionrelates to'drain connections s ubsg basinsj ankl the llke.

l ygw describe the-mvent on as in connection With as nk, but it-is to I t rat theinvention 1s applito tu-bs'or any other tubs Ge -Mm ioutjlthis specification for the sake 3 cipally oonnection ithhigh-graide sinks or, tilibsgt' eIinnersuffacfescf Whichare covered' lt'reoi'isenamel Because of the chali'fect'er offth diam" connections which suitjace'imiayfbeL made entirely free from, Shari angles for Q abr'u n t changes n d irectlon.

lly strut M y cer iyfportions of the fittlng protrude separate f, rn ,,the sinks are so core; ed and arran ed 'that when'ln position 4.5 also e rthe norn'ial innejr bottom surface of i rstiitdaii i 10, Qieoe;

sink bottom is provided with a gradual depression surrounding the drain-opening, this depress1on being of. such 'depth that when the drain connection is put in position thehighest ,portion of the connection- Within the sink is approximately level with the main. inner bottom surface of the sink. By this-arrangement any utensils placed in the sink will; stand perfectly level'whether placed'over or near the drain opening or not.

Another object accomplished'by the invention is the construction and, arrangement: of

the parts ofthe Connection so that although,

as has beensta'ted, a portionfof thecon'ne'c tion "protrudes abovethe' inn-er bottom surface of the sink. the entire fluid contents of the sink may pass out through the drain opening Without the fittlng." v

The use of our invention avoids any tendency to chip or craze th'e'ehamel surrounding the drain opening and atthe same time 'the appearance of such port-ions of-the connection' as may be seen froin within the sink is Very ornamental and attractive; f

In the accompanying drawing We show an exemplifying structure elmbodyi'n g v the invention. but it is to be understood that the invention is capable of embodiment in different forms.

Figurel is a vertical section through .a portion of a slnk and dram connect on.

Fig. 2 is an elevation ofthe conneetiomthe sink bottom beingshown inse'ction'on the center line of the "drain opening. Fi'gi'B is y a top viewoi the niflplerenioved from the other parts [of "the appliance. Fig. {i is a .top' View of the strainer by itself. V I v Reference character lde'signates the sink or the like. The principal part of the'bottomof the sink is "approximately 'fiat and horlzontalas usual. The dram opening 2.

passes througlrthe sink bottom in any convenient placeyusuall'y near one end. The

opening is usually circular and has per:

fectly straight cylindrical iwalll through the bottomzof the sink.

of the fluid contents from the "sink the impedance by any part of s'ion in thefsink bottom v in openingandjoinin'g thef n imel jti set the is l kx h a rad a bfftlie "class with whichthisjg'enerally ernployed are usually covered on their inner surface with vitreous enamel but the invention is also applicable to vessels which are not so enameled and for tlus reason and for the sake of clearness it is not attempted to show the enamel in the drawing. It is to be noted especially that the inner bottom surface of the sink extends A nipple 5 provided with radially extends ing fingers 6 is passed through the drain opening so that the cylindrical portion of the ni pie 7 extends below the bottom portion of the sink.- The fingers then rest upon the inner bottom surface of the sink adjacent to the opening-g; will be apparent that the separated finger s thus form in effect a radiating i'flange prpvided with one or more openinfgs througligf which residual fluid may drainrom the The tubular portion 7 is exteriorly threaded and a nut 8 engaging the thread compresses a gasket 9 against the bottom of the sink forming a Water seal. The tubular portion of the nipple is discontinned considerably below the inner bottom surface. of the sink and the fingers 6 are widely separated as may be seen in Fig. 3

so that the nipple itself offers no perceptible resistance to the flow of water even at its lowest level through the drain opening. The

nipple 5 has a crossbar-10.

The strainer 11 is of inverted dish shape and preferably has a substantially flat top. The substantially vertical side 12' of the strainer is just deep enough to touchthe inner bottom surface of the sink and enable the top of the strainer to rest on the tops of the finger 6." At the center the strainer is depressed in making it, or countersunk to receive a screw head and a screw 13- passes through the strainer at this point and engages a threaded opening 20 formed in crossbar 10.- The screw-head rests in the countersink flush with the upper surface of. the strainer. The strainer has top openings 14 through which the bulk of the water passes, and side openings 15 which extend to the inner bottom surface of the sink and permit the escape of water after its level is lower than the top of the strainer. \Vithout these side openings in this kind of a drain connection some of the fluid would be trapped in the tub by the strainer. The fingers 6 and the bottom of the side wall of the strainer rest on the. bottom of the depression 3 ad jacent to the drain opening and the depth of the depiression is so calculated that, as

shown in ig. 1, the top of the strainer is approximately ,level with the main inner bottom surface of the sink. By this arrangement any utensils placed in the sink over or near the drain opening may rest perfectly level, the same as if no part of the connection projected within the sink.'

The drain pipe 10 may be connected to the nipple in any-convenient way but In a preferred construction the pipe is provided with a flange 17 which rests against the end of the nipple and a nut 18 engaging the screw thread on the nipple has a flange 19 1nwardly extending andengagmg flange 17 and serving to urge the latter tightly agalnst the end of the nipple.

lVe claimz- 1.'The combination of an enameled sink provided with a drain opening surrounded by a gradually sloping depression, a drain pipe and a connection intermediate the drain pipe and the sink at the dram open ng, a portion of the connection extending within the sink above the bottom of said depression,

2. The combination of an enameled sink provided with a drain opening surrounded by a gradual depression, a drain plpe and a connection intermediate the drain pipe and the sink at the drain opening, a portion of the connection extending within the sink above the bottom of said depression, so that the highest portion of the connection is substantially level with the main inner bottom surface of the sink.

3 The combination ofa sink, provided with a drain opening and a depression surrounding the opening, a nipple passing through the opening and having members engaging the inner bottom surface of the sink adjacent to the opening, -.a water seal intermediate the nipple and the sink bottom and a strainer secured to the nipple, the top of the strainer being substantially level with the principal portion of the inner sink bottom;

4. The combination of a sink, the bottom of which is provided with a circular drain opening and a shallow depression surrounding the opening, a nipple passing through the openin and provided with fingers resting on the bottom of the depression adjacent to theopening, a nut engaging a screw thread on the nipple below the sink bottom, a water seal intermediate the nut and the outer bottom surface of the sink, a strainer inclosing the drain opening and the fingers on the nipple, the strainer being provided with top perforations and side perforations adjoining the inner surface of said depression and means for securing the strainer to the nipple.
